I see similar things like this normally and when I zoom in on cell phone pics they are everywhere, either they are really there or I really have gone mad. Some are little people, almost like little blue gremlin imps that like to knock things out of peoples hands (cups of ice at 7-11 for example) or try to trip people because they think it's funny and that very few people can actually see them and those who do are considered crazy if you say anything about it.
Wonderful! Very ispiring! I have just started playing with ZB 3.5. And all I know about the whole 3d environment is a bit from a maya class I had in college 2 yrs ago. !0! But you know what?! I am so gonna give this a try. So wish me luck
